clear all;
global FPA Lb Ub Q1 result
fprintf('\nReal Power Loss Minimization\n');
mpc = loadcase('case_ieee30');
NB=length(mpc.bus(:, PD));
NL=length(mpc.branch(:, 1));
fprintf('\nLoad Flow Analysis Using Newton Raphson Method\n');
opt = mpoption('VERBOSE',0,'OUT_ALL', 0);
PL=sum(results.branch(:, PF)+ results.branch(:, PT));
fprintf('\nReal power loss %9.4f MW\n',PL);
fprintf('\nLoss Minimization Using Flower Polination Algorithm\n');
% Dimension of the search variables
Dim=12; popsize=50; N_iter=200;
Lb=[50 20 15 10 10 12 0.95 0.95 0.95 0.95 0.95 0.95];
Ub=[200 80 50 35 30 40 1.1 1.1 1.1 1.1 1.1 1.1];
[result , MinCost] = FPA(Dim,popsize,N_iter,Lb,Ub); // ERROR OCCURS HERE
This program is about using FACTS devices and Flower Pollination Algorithm but when I try to run this code I get error
Insufficient number of outputs from right hand side of equal sign to satisfy assignment.
Error in File (line 21)
[result , MinCost] =FPA(Dim,popsize,N_iter,Lb,Ub);

As per my understanding, you are getting an 'Insufficient number of outputs from the right-hand side of equal sign to satisfy assignment' error. The error indicates that the right-hand statement, i.e. FPA(), is giving fewer outputs than the number of outputs you are trying to assign, which is [result, MinCost].
The possible workaround for this would be to remove one of the output variables. If you are not sure about the output argument of the function FPA(), it would be best to check out the documentation.
